The lost nostalgia of postcards is sad, indeed. I was always fascinated by them, too, and spent many an hour in my youth looking at all the postcards in the revolving stand, looking for the best ones for collecting or sending to relatives! I think I must have sent most of them to other folks, because I only have a couple left, in a box somewhere, I think.
I don't go many places these days, and even fewer with those old fashioned post cards. However, if you DM me your address on Discord, I will keep you in mind the next time I am near a postcard rack! 😊
